Tire pressure light

[GCTahoelyfe1911]

I’ve had my 2019 Chevy Tahoe LT for just a year now. Over the last 2 weeks the tire maintenance system lights have turned on. I’ve added air but the light stays on and I keep getting the alert every time I start th vehicle.

I would recommend reading the TPMS code with a capable scanner. If there's a message or light, there's a code. You may have a failed sensor or something else, but the only easy way to tell is to read that code.

Pics of the truck, please.

You are already receiving sage advice from the knowledgeable folks on this Forum.

You say that you've added air, but was the pressure down below recommendations before you added air? Could there be a leak?

The batteries go dead in the in-wheel sensors. You can have the tire shop replace them. The best deal right now is at Walmart as they are charging $12/sensor.

press the buttons on the steering wheel until you get to tpms, it will show you the tire pressure readings, usually when this happens one will read 00 and that is your bad one.
normally it is on 2 pages so i.e. FL:32, FR:32, click again, RL:32, RR:00 that would indicate right-rear is not reading

I had the same issue with my 2019 Tahoe at around 80K miles.
The dealer replaced the bad sensors and rebalanced the tires N/C under GM warranty as a “safety related item.”

Funny, my 2019 Yukon just lit up yesterday. No reading on one sensor. Sensors on my wife's 2011 Malibu still going strong.
